How to Use the Blocklist Feature to Control Your Outreach
Prevent outreach to specific contacts or entire companies by managing your blocklist in Instantly.
What is the Blocklist?
The blocklist feature allows you to exclude specific people or entire companies from your outreach campaigns. This ensures you never accidentally reach out to the wrong contacts.
Who Should You Add to Your Blocklist?
Consider adding:
Your existing customers - Avoid sending cold outreach to people who already work with you
Past unsubscribers - Respect people who previously opted out (though these are automatically added)
Specific companies - Exclude organizations you don't want to target for any reason
Personal contacts - Block colleagues, partners, or anyone else you shouldn't contact through cold outreach
How to Add Contacts to Your Blocklist
Step 1: Navigate to the blocklist page
Step 2: Prepare your CSV file
You can upload contacts in two ways:
Individual emails - Add specific email addresses (like [email protected]) to exclude just that person
Entire domains - Add domain names (like company.com) to exclude everyone at that organization
Step 3: Upload your CSV
Click the upload button and select your prepared CSV file. The system will process your blocklist additions.
Important Notes
All unsubscribers are automatically added to the blocklist, so you don't need to manually upload them
Domain-level blocking is powerful - if you add "company.com," no one with an @company.com email will be contacted
You can update your blocklist at any time as your needs change
